ASE/ASI API for AutoCAD 2020

[miguel.aguilera]

I'm planning to migrate an AutoCAD 2016 ObjectARX application, wich uses ASE/ASI API, to AutoCAD 2020.
The problem is that I can't see neither the corresponding headers nor the aseapi23.lib and asiapi23.lib in the AutoCAD 2020 ObjectARX SDK.
Are those API's deprecated and no longer available or it's available in other location?

These API's are deprecated long ago, the current technology available for manipulating the entity links/data
sources etc is CAO API. This API is an ActiveX Automation API, hence can be
used from VLISP, VB or VC++. Please look in the help file  for
more on the CAO API.
And for database access you can use any of the industry standard database
connectivity API's.

Thank you very much for the clarifications.
